A New Chapter in the Altitude Collection
The Altitude Chronograph Pulsograph Valjoux 23 brings a low-volume, hand-wound chronograph into Bremont’s Altitude collection, placing a historically significant movement within the brand’s contemporary tool-watch design.
Positioned alongside the MB aviation line, it broadens the Trip-Tick case family for enthusiasts who want a traditional hand-wound calibre in a modern titanium case with everyday practicality.
The Valjoux 23 at the Core
At the heart of the watch is the Valjoux 23, a column-wheel chronograph calibre first produced in 1916. This 13-ligne movement, recognised for its Y-shaped bridge, elongated levers and large balance, powered chronographs from houses such as Patek Philippe, Audemars Piguet, Rolex and Vacheron Constantin before production ceased in 1974.
Bremont has sourced ‘new old stock’ examples and, with Jean-François Mojon’s Chronode atelier, turned 40 ébauches into finished, regulated movements with grained and sandblasted surfaces, chamfered edges and polished details.
Dial Architecture and Pulsograph Identity
The textured salmon galvanic dial recalls mid-century chronographs with a vertically brushed centre, grained outer ring and silver bicompax sub-dials. Applied stencil-style numerals in polished black gold are filled with white Super-LumiNova, with a 30-minute counter at 3 o’clock and running seconds at 9 o’clock bearing Bremont’s three-pronged propeller motif.
A pulsometer scale encircles the dial in reference to doctors’ chronographs once used to measure heart rate, many of which relied on the Valjoux 23, linking the movement directly to the watch’s pulsograph identity.
Titanium Trip-Tick Case and Wearing Experience
The 42 mm brushed titanium case uses Bremont’s Trip-Tick three-part construction, a hallmark of the Altitude line, with a length of 49.62 mm and depth of 12.52 mm. The Valjoux 23’s slimness helps deliver a profile that wears comfortably while retaining presence.
An exhibition caseback reveals the reworked movement backed by a decorated titanium element, and the watch is water-resistant to 100 metres (10 ATM). The 22 mm lug width allows straightforward strap changes, while a quick-release brown nubuck leather strap with ecru stitching complements the salmon dial.
Technical Specification
The hand-wound Valjoux 23 inside the Altitude Chronograph Pulsograph runs at 28,800 vibrations per hour (4 Hz), has 25 jewels and offers a 48-hour power reserve. It drives central hours and minutes, chronograph centre seconds, small seconds at 9 o’clock and a 30-minute counter at 3 o’clock beneath a glass box anti-reflective sapphire crystal.
Numerals and indexes are filled with white Super-LumiNova with blue emission, paired with black gold hands and a propeller-style running seconds hand. The edition is capped at 40 pieces, reflecting the availability of the NOS Valjoux 23 movements and positioning it as a focused collector’s chronograph within the Altitude line.
Design Philosophy and Brand Context
Bremont presents the Altitude Chronograph Pulsograph Valjoux 23 as a watch that blends classic chronograph cues with the robustness of the Altitude range, rather than recreating a single historic reference. Founded in 2002, Bremont centres on tool watches across air, land and sea, and channels that ethos into a hand-wound chronograph intended for enthusiasts who want historical calibres in everyday-wearable cases and value the heritage of the Valjoux 23.
Why It Matters
For collectors in the GCC, the Altitude Chronograph Pulsograph Valjoux 23 unites a historically important chronograph calibre with a contemporary titanium sports case in a 40-piece edition. Its salmon dial, pulsometer scale and hand-wound NOS movement offer mechanical depth and rarity aligned with regional preferences for discreet exclusivity.
